This new process requires the internal collaboration of an internal quality assurance reviewer and the instructor$$s Department Chair, as well as an external independent subject matter expert. The internal quality assurance reviewer starts with a new case in which she interviews current students of the instructor in question. In the meantime, the Department Chair requests an assessment from an external expert who should evaluate the teaching material provided by instructor. The Chair waits a maximum of $3$ days for the answer. If a response does not arrive within this timeframe, the Chair must ask another expert. Finally, if an expert does respond, he sends his assessment back to the Chair. It will then be forwarded to the internal quality assurance reviewer. The internal quality assurance reviewer re$-$examines the data from the student interviews, the course evaluations from the university Online Course Evaluation System $($OCES$),$ as well as the expert assessment, then develops a summary report. While the internal quality assurance reviewer prepares the report to be submitted to the Faculty Dean, the Chair fills in a check to pay the external expert.
